There is 64,500,000 square kilometers of habitable land on Earth, or about 43% of the total land area. Thanks to modern technology, about 40% of this livable area is now cultivated or grazed and about 3% is covered by human settlements. In other word, the ecological system has been radically changed on about 43% of livable land. As a result, there are currently about 7.5 billion people living on the planet, more than 3 times the number since the Second World War. The total biomass of the people on Earth today is about 300 million tons, which means that 96% of the total biomass of mammals on earth is humans or livestock (cows, pigs, etc.) and only 4% are wild mammals.To put it another way, there are currently an average of 116 people living on every habitable square kilometer of our planet.
Due to the increased biomass of the humans and livestock and of the population density and livestock density and the huge growth of cultivated and grazing land, our global ecological system favors the emergence and multiplication of new crop diseases, new livestock diseases, and new human diseases. Thus, new and ever-new pandemics of animal origin (zoonotic pandemics) will inevitably follow the current covid-19 pandemic. An increase in the share of big monocultural farming units in total farming and an increase in the monocultural mass production of food-producing animals will increase the efficiency of this disease production.
It is therefore very possible that more and more people will suffer in new pandemics of animal origin and also due to food shortages, caused by increasing animal and plant diseases. Thus, the modern technology may help to reduce population pressure in this way as well.
2.Some optimists also think that technology can even make it possible for the entire population pressure to stop. Indeed, it is possible that the continuing impoverishment of the biosphere and global warming made possible by technological development will eventually lead to the collapse of the global ecological system to which Man belongs. After that, there will be no population pressure in any of the forms we know today.
